Y 'cAsnMENr HINGE.

Application led September 30, 1925. Serial No. 59,718.

the. window or door pivoted'thereby in a' certain position.

It is another object ofy this invention to provide a hinge havinga pairof members hinged'together, each having a clamp plate associatedtherewith and having means for clainping'said clamp plates together.

Other objects and advantages of the invention will be made evidenthereinafter. Referring to the vdrawings in which- AI illustrate myinvention Fig. lis a diagrammatic view showing the utility of theeasement hinge of my` invention.

Fig.` 2 is an elevational view'o'f the A`casement hinge of lmyinvention.

Fig. 3 is a section'taken'onthe rline of Fig. 2.

Fig. 4 is a fragmentary section showing the manner in which'the hingemembers arey clamped so. as to be relatively non-swingable.

In Fig. 1 I show a easement 11 surrounding an opening 12 which is closedby a swinging member such as a door or easement window 13. The member 13is hingedly secured to the Casement 11 by means of a easement hinge 15incorporating the features of my invention.

lith reference to Fig. 2 the hinge 15 has a primary hinge member 18 anda seconda-ry hinge member 19. The primary hinge inember 18 is preferablysecured to the easement 11 by means o'f screws 2O which are projectedinto the easement 11 through openings 21 provided in the primary member18. The secondary hinge member 19 is secured to the member 13 by screws23 which are extended into the member 13 through openings 24 provided inthe secondary hinge memberl 19. The primary hinge member 18 has a pairof outer cylindrical portions and the secondary hinge member 19has acentral cylindrical portion 26 which is placed between the outercylindrical portions 25 of the primary hinge member 18. A hinge pin 27is extended` through the cylindrical portions 25 and 26.01: the primaryhinge meinbei 18 and the secondary hinge member 19 for -hingedlyattaching-these members together. A plug 28 is inserted into the lowerpart of the lower cylindrical portion 25 of thc primary hinge member 18.pin 27is preferably secured rigidly to' the lower outer cylindricalportion 25 of the primary hinge member 18.

The primary hinge 'member 18 is provided with anotch 30 and thesecondary hinge member 19 is provided-with a notch 31 which alignswith-the notch 30,` asclearlyfshown in Fig. 2Q Placed inthe notches 30and 31 concentric with respect to the hinge pin 27y isalower clampplate33 the hinge pin 27 extending through a central threaded Opening 34of the lower clamp plate 33. As clearlyshown iii-Fig. 4,the lower partof the pin 27 is smaller in diameter than the upper part,

vwhich upper part is threaded at 35 to permit the lowersclamp plate toYbesecured thereto. The primary hingeplate V18 has .".t'projection4l3''which 'extends and lits loosely in a lslot 37 formedfin. theperiphery ofthe lower clampplate 33. A lower facej 38 of the yclampplate' 33 engages a face`39 ofthe primary hinge member 18, which' face.39y defines 'the y'lower' part vofthelnotch 30. Anupper clampplate"41is"placed in thenotches 30 and 31, having a concentric opening42 through which the pivot pin 27 extends. The upper clamp plate 41 hasa slot 43 into which a projection 44 of the secondaryhinge member 19extends, this projection 44 fitting loosely in the slot 43. An upperface46 of the upper clamp platev41 is engaged by a face 47 of thesecondary hinge plate 19 which confines the upper part of the notch 31.A lower face 49 of the upper clamp plate 41 is adapted to rest inengagement with the upper face 50 of the lower clamp plate 33.

When the hinge'is in non-clamping position, as shown in Fig. 2, there isa space 52 between the lower face 38 of the' lower clamp plate 33 andthe secondary hinge member 19, and there isa space 54 between the upperface 46 of the clamp plate 41 and the lowerface of an arm 55 of theprimary hinge member 18. j y

The upper end of the pivot pin 27 is threaded as indicated at 577, and aclamp nut 58 is threaded thereonto, a lower face 59 of The hinge Cil thenut 58 engaging an upper face 60 of the arm 55 of the primary hingemember 18.

In Figs. 1, 2 and 3 the primary and secondary hinge members of myinvention are not clamped together and therefore the member 13 is freeto swing on its pivot. IVhen it is desired to retain the member 13rigidly in a certain position, the nut' 58 is advanced downward en theupper end 57 of the pivot pin` 27 so that the parts occupy a position,as shown in Fig. t. With reference to Fig. 4t, when the nut 58 isadvanced downward on the pivot pin Q7, the pivot pin is' moved upwardrelative to the parts of the hinge.V Since the lower clamp plate 33 isrigidly secured thereto it is moved upward with. the shaft. The upperclamp plate t1 is lifted by the lower clamp plate 3?) and is broughtinto engagement with the lower face of the arm 55.

At this time the upper face of the lower clamp plate 33 is forced firmlyinto engage ment with the lower face 49 of the up 3er clamp plate 41.Suiiicient friction is thereby obtained between these two faces toprevent a relative swinging ofthe primary and secondary hinge members 18and 19 which are locked to the lower and upper clamp plates 38 and 41,and therefore the member' 13 is locked in any desired position asindicated by dotted lin-es 6st inig. 1.

From the foregoing description the utility of my invention is plainlyevident. The design of the hinge 15 is rather attractive and can be madein any proportion to suit the needs. The nut 58 is so situated that itis easily operated and the hinge may be readily locked in any desiredposition.V The different parts of my invention are readily assembled anddismantled. It is preferable to make the threads on the lower part ofthe enlarged portion of the hinge pin 27 eoarser than the threads 57 atthe upper end thereof so that in operating the nut 58 the hinge pin willnot be loosened in the opening of the lower clamp plate 33.

I claim as my invention :f Y

1. A hinge of the class described comprising: a primary hinge member; asecondary hinge member; a hinge pin by which said ,primary and secondaryhinge nembers are hingedly secured together; a lower clamp plate adaptedto be engaged by and moved with said primary hinge member; an upperclamp plate adapted to rest in 'engagement with said lower clamp plate,said upper clamp plate being adapted-to be engaged by and to move with.said secondary hinge member; and means for clamping said upper andlower clamp plates from relative rotation, said primary and secondaryhinge members having adjacent notches into which said upper and lowerclamp plates extend. 2. A hinge of the class described comprising: aprimary hinge member; a secondary hinge member; a hinge pin by whichsaid primary and secondaryrhinge members are hingedly secured together;a lower clamp plate adapted tovbe engaged by and moved with said }jrimary v hinge member, said hinge pin being rigidly secured to saidlowerclamp plate; an upper clamp plate adapted to rest in engagementwith. said lower clamp plate; said. upper c lampA plate being adapted tobe engaged by and to move with said secondary hinge member; anda nutadapted to be advanced onto a threaded end of said hinge pin in a mannerto force said lower clamp plate into non-movable contact with said upperclamp plate.

vIn testimony whereof, I have hereunto set my hand at Los Angeles,California, this 24th day Orsept i925. y
